This form of protection caused great inconveniences for buyers of the game, be it on the internet connection end or a takedown of the Ubisoft servers. While the DRM was causing grief for real buyers of the game, it did keep the pirates at bay for far longer than the usual PC game. But the game hackers have finally cracked it.

Cracking group known as Skid Row claims to have created a crack that removes the required internet connectivity from Assassin's Creed II. Some other cracks emulated Ubisoft's servers, fooling the game into thinking it was authenticated. Skid Row, however, said in its nfo notes that its crack cannot be compared to other emulation cracks, as "does not construct any program deviation or any kind of host file paradox solutions."
